deba69d022 Handle all shortcuts in the same function
Shortcuts are sometimes initiated from a keycode event, and sometimes
from a text input event.

Move the handling to a unique function.

1faf6cfd9d Rename the server scrcpy-server.jar
The server is built as an APK to simplify the build, but in fact this is
a simple jar (it is not even signed).

In order to avoid confusion, rename it to .jar, so that users do not try
to "adb install" it.

Also rename it from "scrcpy" to "scrcpy-server" to distinguish from the
client-side.

2172c53b7b Force the server target filename
The server path may be customized using SCRCPY_APK. If its basename is
different from "scrcpy.apk", it will be pushed with a different name,
so the execution would fail.

Therefore, force the push target filename.

ca44585f96 Do not send simple mouse move events
Moving the mouse without any button pressed has no effect on Android.

274e1ac9ec Fix rotation bug in fullscreen mode on X11
On rotation, scrcpy resize the window to match the new rotation.
However, in fullscreen mode, setting the window size does not change the
windowed size on X11, so the behavior is incorrect.

To avoid the problem, apply the resize only after fullscreen is
disabled.

60b2f2ca64 Indent switch blocks content
For readability, indent "case" in switch blocks.

Replace:

    switch (x) {
    case 1:
        // ...
    case 2:
        // ...
    case 3: { // a local scope block
        int i = 42;
        // ...
    }
    }

By:

    switch (x) {
        case 1:
            // ...
        case 2:
            // ...
        case 3: { // a local scope block
            int i = 42;
            // ...
        }

865ebb3862 Encode video using MediaCodec API
Replace screenrecord execution by manual screen encoding using the
MediaCodec API.

The "screenrecord" solution had several drawbacks:
 - screenrecord output is buffered, so tiny frames may not be accessible
   immediately;
 - it did not output a frame until the surface changed, leading to a
   black screen on start;
 - it is limited to 3 minutes recording, so it needed to be restarted;
 - screenrecord added black borders in the video when the requested
   dimensions did not preserve aspect-ratio exactly (sometimes
   unavoidable since video dimensions must be multiple of 8);
 - rotation handling was hacky (killing the process and starting a new
   one).

Handling the encoding manually allows to solve all these problems.

89f6a3cfe7 Handle resized video stream
Accept a parameter to limit the video size.

For instance, with "-m 960", the great side of the video will be scaled
down to 960 (if necessary), while the other side will be scaled down so
that the aspect ratio is preserved. Both dimensions must be a multiple
of 8, so black bands might be added, and the mouse positions must be
computed accordingly.

8984c1a7c4 Scale mouse events
The video screen size on the client may differ from the real device
screen size (e.g. the video stream may be scaled down). As a
consequence, mouse events must be scaled to match the real device
coordinates.

For this purpose, make the client send the video screen size along with
the absolute pointer location, and the server scale the location to
match the real device size before injecting mouse events.

11a60e5767 Keep screen info in cache
Currently, we only use screen information (width, height, rotation)
once at initialization, to send the device size to the client.

To be able to scale mouse events, make it accessible in memory. For this
purpose, replace the "static" DeviceUtil to a singleton Device, and
update it on every screen rotation.

53cd59605a Ignore keycodes generating unwanted events
Ctrl, Alt, Shift and Meta should not be transmitted to the Android
device: they may generate unwanted events. For instance, resizing the
window using Alt+click will generate an Alt event which may open a menu
on the device.

All keycodes that generate a text input must also be excluded, to avoid
the text input to be written twice.

cabb102a04 Implement keyboard/mouse control
To control the device from the computer:
 - retrieve mouse and keyboard SDL events;
 - convert them to Android events;
 - serialize them;
 - send them on the same socket used by the video stream (but in the
 opposite direction);
 - deserialize the events on the Android side;
 - inject them using the InputManager.
